Microsoft is investigating new public reports of a possible vulnerability in Microsoft Windows SharePoint Services 3.0 and Microsoft Office SharePoint Server 2007. The vulnerability could allow an attacker to run arbitrary script that could result in elevation of privilege within the SharePoint site, as opposed to elevation of privilege within the workstation or server environment.

We are actively working with partners in our Microsoft Active Protections Program (MAPP) to provide information that they can use to provide broader protections to customers.

Upon completion of this investigation, Microsoft will take the appropriate action to help protect our customers. This may include providing a security update through our monthly release process or providing an out-of-cycle security update, depending on customer needs.
